The present investigation evaluates the neuroprotective effect of chlorogenic acid (CA) in alcohol-induced brain damage in neonatal rats. Ethanol (12 % v/v, 5 g/kg) was administered orally in the wistar rat pups on postnatal days (PD) 7-9. Chlorogenic acid (100 and 200 mg/kg, p.o.) was administered continuously from PD 6 to 28. Cognitive function was estimated by Morris water maze (MWM) test. However, activity of acetylcholinesterase, inflammatory mediators, parameters of oxidative stress and activity of caspase-3 enzyme was estimated in the tissue homogenate of cerebral cortex and hippocampus of ethanol-exposed pups. It has been observed that treatment with CA attenuates the altered cognitive function in ethanol-exposed pups. There was a significant decrease in the activity of acetylcholinesterase in the CA treated group compared to the negative control group. However, treatment with CA significantly ameliorates the increased oxidative stress and concentration of inflammatory mediators in the brain tissues of ethanol-exposed pups. Activity of caspase-3 enzyme was also found significantly decreased in the CA treated group compared to the negative control group. The present study concludes that CA attenuates the neuronal damage induced in alcohol exposed neonatal rat by decreasing the apoptosis of neuronal cells.
本研究评估了绿原酸(CA)对新生大鼠酒精诱导脑损伤的神经保护作用。在出生后第7至9天,对Wistar大鼠幼崽口服给予乙醇(12% v/v,5 g/kg)。从出生后第6天至28天,连续给予绿原酸(100和200 mg/kg,口服)。通过莫里斯水迷宫(MWM)试验评估认知功能。然而,在暴露于乙醇的幼崽的大脑皮层和海马组织匀浆中,估计了乙酰胆碱酯酶的活性、炎症介质、氧化应激参数和半胱天冬酶-3酶的活性。据观察,CA治疗可减轻暴露于乙醇的幼崽认知功能的改变。与阴性对照组相比,CA治疗组乙酰胆碱酯酶的活性显著降低。然而,CA治疗显著改善了暴露于乙醇的幼崽脑组织中氧化应激增加和炎症介质浓度升高的情况。与阴性对照组相比,CA治疗组半胱天冬酶-3酶的活性也显著降低。本研究得出结论,CA通过减少神经元细胞凋亡减轻了酒精暴露新生大鼠中诱导的神经元损伤。
